Here we go again. The dealer has replaced my water pump three times due to its coming on for a couple seconds about every minute. They have checked for leaks. I have checked for leaks. There are none.

Every time I get a new pump it works well for a few months and then starts doing it again. I was just on a one month trip and it worked great the whole time. Then I drove to Los Angeles last week and it started again.

This is so frustrating.

Anybody else have this problem?

It might be that the pressure cutoff switch is either defective or needs adjusting, however you say that one than one pump causes the same problem so that might be a remote possibility.

You might have a leak that is difficult to source - is there any water on the ground under your unit?

I really have no clue in this one either. Pump works for a few months, then it starts to do this - do you keep it on all the time? If you are hooked to city water, the pump should be turned off.. You probably already know that, but it was something I didn't for awhile. I'm sure someone here can help.

1) water leaking from your outside city water inlet
2) leaks at the outside shower
3) leaks at fittings in the camper

Then you must look at the water source.

If you are using a well to fill your fresh water tank, fine silt may be clogging/eroding the check valves in the pump causing pressure to leak back into the fresh water tank. This will cause regular cycling of the pump.

My suggestion is on your next pump (this one may be shot again) to put a high micron filter between the sand (screen) filter and the pump itself.

OR

Buy a high micron filter for your fill hose.
Completely drain your fresh water tank and flush it out with LOTS of FILTERED water.
Replace your inlet screen filter and pump (again - sorry).
Fill ONLY with filtered water from that source in the future.
